Hab. South Africa. 



I have not seen any specimen, or even a skull, of this species, and 

 I do not believe there is one in any European Museum. 



Camper probably knew B. Oswellii. He observes, " Cornu an to- 

 nus A D in hoc specimine incurvum adeo fuit ut alterum E F H, 

 tamquam inutile reddiderit. Verum non ita in omnibus ; possideo 

 alterius cranii partem, cujus cornu anterius rectum, et antrorsum 

 inclinatum est." — Camper, I.e. p. 186. 



Mr. Baines gave a foetus of the Kobaaba to the Roj'al College of 

 Surgeons (killed 3rd of June, 1862). He has shown me a series 

 of drawings of the recently killed Kobaaba. One group represents 

 the R. sinms and i?. Osivellii side by side. The horns of the two are 

 very different in ajipearance. 



Mr. Baines saj's Mr. Chapman was informed by the natives that 

 they had never seen a young Kobaaba = C. Oswellii. Mr. Baines 

 says that it is possible that the horn, being worn away at the end 

 by the constant friction on the front as it passes through the bushes, 

 may bend forward in the older specimens. The Kaffii'S make the 

 boms of the cattle bend by scraping them on the sides towards which 

 they wish them to turn. 



Schinz gives the name of niger to the Rhinoceros horn figured by 

 Andersson ; but he describes it as curved back, in the same words as 

 he described the horns of the other African species. 



Camper compares the labial process to a finger, and says it is not 

 unlike the lobe at the end of the trunk of the Elephant. 



See M. F. Fresnel's " Sur I'existence d'une espece unicome de 

 Rhinoceros dans la partie tropicale de I'Afrique " (Comptes Rendus, 

 xxvi. 1848, p. 281). See also A. Smith's ' Hlust. Zool. S. A.' t. 1, 

 where he says the natives mention a one-horned African species.

 nasal, internasal, and the intermaxillaries nnited into one inass. Asia 

 and Europe, fossil. 



5. CCELODONTA.

 bones broad, rounded in front ; cutting-teeth none ; intermaxillaries
